Overview
01
What are chain guide rails
Profile chain guide rails are guiding rails made of polyethylene (PE UHMW) or galvanized metal profiles, on which the chain slides in conveyor systems - reducing friction and wear compared to direct metal-to-metal contact. Nibora Ltd. offers several profile families (T, E, BL, U, CT, C10P, COMBI), each sized to match a specific chain size (ISO code).

What material are chain guide rails made of?
Mainly polyethylene PE UHMW (operating temperature up to 80°C); some profiles (C3, C5, C9, C10) are also available galvanized or in stainless steel AISI 304.
How do I choose the right guide profile?
By the chain size (ISO code) and the conveyor's mounting type - each profile (T, E, BL, U, CT etc.) has a different cross-section shape suited to a specific rail construction.
